On the Unexpected Behavior of a Common Gas Chromatographic Phase
Carbowax 20M was coated on Chromosorb W, heat-treated at 280°, and exhaustively extracted. The remaining support performed chromatographically in a manner similar to highly efficient, well deactivated gas-liquid chromatographic packings, even though the non-extractable polymer film was too thin to permit reliable combustion analysis. This phase was well suited for the analysis of polar compounds, producing symmetric, sharp peaks with very short retention times. A strong surface effect was evident, which could be utilized for otherwise difficult separations. © 1973.
